  • Interview with AusBiz for TrulyAus Magazine

    Q&A WITH ABBY CRAWFORD OF AUSTRALIAN POWER EQUIPMENT by Emily Riches | May 22, 2024 | Business Abby Crawford and Andrew Cockbain are the driving forces behind Australian Power Equipment, a leading provider of low, medium and high-voltage power solutions. We chatted to Abby about their journey so far, the importance of sustainability and what’s next for their business. Can you tell us a bit about your background, and how you came to found Australian Power Equipment? It’s a bit of a funny story! We started the company during Covid with just one product: the Cambria Association for the Blind (CAB) cable management systems. Both Andrew and myself were working full-time in consulting roles and thought this would give our respective kids a chance to learn new business skills. It turns out we ended up running it as a small side business instead. It wasn’t long before we took on the agency for B&D transformers and within the year had also added Üntel Kablo cables and Leistung Energie switchgear. The business grew rapidly from there, and now we have both worked full-time in the company for more than two years. Andrew is an electrical engineer with an extensive background in providing power solutions to mining and infrastructure projects. My background is in business management and development, from multi-national organisations to smaller start-ups – so I have loved the journey of starting and growing Australian Power Equipment. Australian Power Equipment is renowned for its quality equipment. Can you talk us through some of the equipment you offer and your unique approach to addressing urgent equipment needs? Safety and reliability is critical in our industries, and we supply the highest quality equipment certified to Australian and IEC standards. We offer all manner of industrial cable, transformers, switchgear and substations. The most important part of our supply chain is building teams based on mutual values, trust and a commitment to quality and delivery. Our critical sourcing services offer immediate solutions to critical issues. New equipment takes time in manufacturing and delivery, and there are many situations where sites simply can’t be shut down. We utilise our in-stock products, refurbished second-hand equipment and connections to provide quick solutions. A recent example was a major mine client that urgently required a critical electric drive; we sourced the part and had it flown into the country within three days. One of the core pillars of your business is a commitment to sustainability. Why is sustainability important to you and can you share some specific initiatives or strategies you’ve implemented? Sustainability is more than a buzzword to us: it is a core value. Our critical sourcing and second-hand division focuses on a circular-economy model. Our new equipment focuses on sustainable fuels, and net-zero carbon footprint. We also work with our supply chain to assist in creating sustainable pathways. Our greatest joy is our community and environment initiatives. We are sponsors of Aussie Ark and have partnered in their endangered Broad Headed Python project, sponsoring an Indigenous ranger to assist in managing their capture, breed and release program. We are also a Primary Sponsor of Taronga Conservations Society Australia and we are very excited about the projects they are running.  Protecting our native Australian wildlife is extremely important to us. You recently received an Australian Enterprise Award – congratulations! What projects are on the horizon for Australian Power Equipment as you continue to grow? Thank you! It was wonderful to be recognised with the award. We are growing in many directions. We pride ourselves on our customer service, and as a small team we can be very agile in our approach.

  • Navigating International Shipping Challenges: Australian Power Equipment Offers Solutions

    Last night was the 26th attack on commercial shipping on the Red Sea since 19 November, the largest to date. In recent weeks, the world has witnessed a surge in security threats impacting global trade routes, leading to significant changes in shipping dynamics. The assaults by Houthi rebels in Yemen on commercial vessels navigating the Bab al-Mandab Strait have triggered a ripple effect on the world’s busiest international shipping lanes. The Houthi attacks, primarily targeting ships headed to Israel, have compelled numerous firms such as Maersk and BP, to alter their shipping routes, avoiding the Bab al-Mandab Strait and opting for a longer journey around Africa’s Cape of Good Hope. This shift has increased travel times from an average* of 25.5 days to approximately 34 days, affecting the 17000 ships that pass through the Suez Canal annually.  This represents 12% of global trade, valued at over $1 trillion. While this situation undoubtedly affects international shipping to and from European destinations to Australia, the repercussions extend beyond the altered routes. Australian Power Equipment is witness to the multifaceted challenges placed on global trade and the impact this has on the shipments of high-quality, reliable infrastructure equipment from Europe to Australia. Working with the best advisors has seen them plan effective shipping methods and able to forecast and anticipate further delays.

The upcoming Chinese New Year celebrations pose an annual challenge notorious for its impact on manufacturing and shipping delays, further compounding the issue. However, the most pressing concern for Australia lies in the ongoing industrial action at its ports, presenting a significant barrier compared to the Red Sea attacks or Chinese festivities. According to Freight and Trade Alliance director Paul Zalai, industrial action taken by maritime unions in Australia against stevedore DP World is costing the local economy an estimated $20 million per day**. Strikes and work bans across Australian ports have led to a backlog of tens of thousands of containers, causing week-long delays in shipping. Facing the reality of these shipping challenges, Abby Crawford, Director of Australian Power Equipment, acknowledges the limited control over external factors. However, she emphasises the importance of proactive planning to mitigate disruptions: “We can’t do anything to overcome the reality of these international shipping delays.  The advice we give our clients is to expect increased shipping timeframes and costs, and factor this into the project deliverables”.

  • The Outdoor 11kV Neutral Earthing Resistors: Functionality and Calculation

    In the realm of high-voltage power equipment, neutral earthing resistors play a crucial role in maintaining the safety and reliability of electrical systems. Australian Power Equipment can provide outdoor 11kV neutral earthing resistors that stand out for their ability to handle up to 250amps. In this article, we look at the concept of neutral earthing resistors, explore their purpose, mechanism and delve into the calculations involved in determining their optimal value. What is a Neutral Earthing Resistor and its Purpose? A neutral earthing resistor (NER) is an essential component in power distribution and transmission systems. Its primary purpose is to limit the fault current that flows through the neutral point of a power system when an insulation fault or ground fault occurs. By intentionally introducing resistance in the path of the fault current, the NER prevents excessive current from flowing and causing potential damage to equipment, electrical components, and the overall power network. This added resistance also serves to reduce the risk of fire and electrical hazards. How does a Neutral Earthing Resistor Work? When a fault occurs in a power system, such as a cable-to-ground fault, the fault current seeks a path of least resistance to return to the source. The NER is connected between the neutral point of the power system and the ground. This connection forces the fault current to pass through the resistor, which limits the magnitude of the current and prevents it from reaching dangerously high levels. The NER essentially provides a controlled path for the fault current to dissipate its energy as heat, thus safeguarding the system’s integrity. Calculating a Neutral Earthing Resistor Value The value of a neutral earthing resistor is a critical parameter that needs careful consideration. It depends on various factors such as the system voltage, fault current, and the desired fault current duration. The resistor value should be chosen such that it limits the fault current to a safe level without causing unnecessary disruption to the power system during normal operations. To calculate the value of a neutral earthing resistor, the following formula can be used: NER Value (ohms) = System Voltage (V) / Fault Current (amps) However, this simplified formula may not consider transient conditions, fault duration or other system-specific aspects. It’s important to work closely with electrical engineers and experts to perform detailed fault studies and simulations to accurately determine the optimal NER resistance value. It’s essential to note that while a lower resistor value provides faster fault detection and reaction, a higher value reduces stress on the equipment during fault conditions. At Australian Power Equipment we recommend NERs limit fault currents to a value that does not cause any further damage to switchgear, generators or transformers beyond what has already been caused by the fault itself. Top 5 things to look for in an Outdoor 11kV Neutral Earthing Resistor Outdoor 11kV Neutral Earthing Resistor, rated for 250 amps, must stand as a robust solution for reliable fault protection. Key features to consider include: 1. Durability: NERs must be built to withstand harsh outdoor conditions to ensure continued operation in diverse environments. Considerations such as Cyclone Wind loading rating and Seismic rating enclosures can be imperative. 2. Precise Resistance: It is critical the resistor’s precisely defined resistance value facilitates accurate fault current limiting and system protection. 3. IP23 enclosures: The resistor’s design should incorporate efficient ventilation that prevents overheating, ensuring prolonged functionality. It should also be designed to keep out birds and vermin. 4. Easy Maintenance: NERS should always be designed for easy maintenance, minimising downtime and optimising system performance. 5. Compliance: It should go without saying that it is imperative they are compliant with AS/NZ 2081 and relevant Mining Standard for Earth-fault current limiters Conclusion Neutral earthing resistors, such as the Outdoor 11kV NER rated for up to 250amps provided by Australian Power Equipment, play a crucial role in safeguarding power distribution systems.By limiting fault currents and preventing dangerous conditions, they contribute significantly to overall system safety. Understanding their purpose, operation, calculation and the features of specialised NER products empower industries to create resilient and secure electrical networks
